Yep. -endpos tells where *in the movie* to stop encoding. The last
5-15 megs of the avi file are not part of the movie, just the index,
so telling mencoder to stop at a point beyond the end of the actual
movie won't do anything...

BTW, your example is rather silly, since 733890560 bytes will easily
fit on a cd with about 5 megs to spare!
